The names of similar products are extremely harmful, Qiqisu, insecticidal, insect sputum, Abadin, Aifuding, Iporin, Insect, and Insecticide.
<Physicochemical properties> The original drug is light yellowish white crystalline powder, odorless, melting point 155-157 ° C, hardly soluble in water, soluble in organic solvents such as toluene, acetone, ethanol and methanol. The product has no acidic or basic functional groups, is stable under normal conditions, does not hydrolyze at pH 5-9, is non-corrosive, and is environmentally safe.
<Poisonous> is low toxicity to humans and animals (preparation), and the original drug is orally administered with acute LD50380 mg/kg. Preparation, rats oral acute LD501210 mg / kg, no carcinogenic, teratogenic and mutagenic effects. It has a certain effect on bees, but the leaves are rapidly photolyzed after 2-4 hours, and are easily decomposed by soil microbial metabolism.
<Formulation> 0.6%, 1%, 1.8% emulsifiable concentrate.
<Control object> Avermectin is mainly stomach poisoning and contact killing effect, almost no fumigation effect, when the pest bites or the insect body contacts the agent, enters the worm through the stomata and the claw pad, causing death, in addition to a certain drive Avoidance. Abamectin has a wide spectrum of insecticidal activity and is effective against a variety of pests and mites, especially aphids, thrips, mites, Plutella xylostella, Liriomyza, and hibiscus. Suitable for the control of crop pests such as vegetables, flowers, fruit trees, bonsai and cotton.
<Usage Method> Abamectin is a new type of natural pollution-free biological Pesticide that is extracted from the soil microorganism, Streptomyces avermitilis, after being fermented in a large tank. After the test, the field concentration is between 10-20ppm, the expected control effect can be obtained, but in the field practical application, the general preparation (content is 0.6-1.8%) in the field due to the participation of various complicated factors. The application concentration is 2000-3000 times, the application amount per acre is 38-25 ml (the application liquid is 75 kg), and the residual effect period is about 7-15 days, such as with mineral oil (such as kerosene, diesel, etc.). Mixed use can reduce the dose and prolong the residual period. The amount of mineral oil mixed is about 0.25% of the pesticide.
